Nema 17 Gearbox

pinshape

We built a custom gearbox for our robotic arm project since they're extremely pricey and hard to find in my area. My friends and I designed the gear ratio to be 1:12, which required six bearings (specifically 624zz), three M3 nuts, and six M4 nuts and screws. Although we haven't fully tested it yet, our initial prints look promising, giving you a starting point to create your own gearbox.
